PROTECTOR FOB, WOUND-YARN-MASS SUPPORTS, &c.

Application filed March 25, 1915.

To all whom it may concern:

lie it known that I, HENRY L. TIFFANY, a citizen of the United States,and a resident of South Dartmouth, in the county of Bristol and State ofMassachusetts, have invented an Improvement in Protectors forlVound-Yarn-Mass Supports, &c., of which the following description, inconnection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

This invention relates to protectors for yarn mass supports and to suchprotected yarn mass as an article of manufacture and sale. 1

The preferred embodiment of my invention is intended mainly for use witha heavy mass of yarn or thread wound in tapering form upon a. markedlytapering, conical support in such manner that the yarn or thread may bedrawn olf axially or substantially so.

Preferably, though not v necessarily, the protector of my invention isemployed with yarn supports of the general character shown in the patentto Charles Gees, No. 986,879, dated March 7, 1911.

In order that the principle of the invention may be readily understood,I have disclosed a single embodiment thereof in the accompanyingdrawing, wherein Figure 1 is a side elevation of a yarn mass wound upona conical support, the protruding tip end of which is protected inaccordance with my invention;

Fig. 2 is a vertical central section of the structure shown in Fig. l;and

Fig. 3 is a plan view thereof.

Cone tubes adapted to receive or have yarn or thread wound thereon andfrom which said yarn or thread is drawn off axially when in uprightposition are customarily formed of paper rolled in one or more layers orcoils into conical form. These tubes are adapted to be mounted forwinding upon taperingarbors of the general shape of the tubes andextending through said tube to within an inch or two of the tip endthereof. The ends of these conical tubes generally protrude somewhatfrom the com plcted yarn or thread mass. A cone tube of this generalcharacter but having an in turned apex end is disclosed in said Gess,

Patent No. 986,379, and I have represented the disclosed embodiment ofmy invention as applied thereto.

The conical tube or axial support is indi- Specification of LettersPatent.

cated at 1, it being formed in any suitable manner and preferably from asegn'ientally shaped blank of paper pulp, papier macho;

or other fibrous material coiled upon itself into a suitable number ofcontacting layers.

The outer surface of the conical tube is preferably superficiallyroughened as inclicated at 2, in order to prevent the slipping ordisplacement of the yarn or thread as the first series of layers thereofare wound upon the tube.

In order to prevent the first laid coils or layers of the yarn or threadfrom contacting with the tip end of the cone tube as they are unwoundtherefrom, the tip end 3 is inturned or upset in any suitable manner, asclearly represented in Figs. 1 and 2. Such tip end should. for effectingthe best results, be very materially inturned, and preferably so assubstantially if not wholly to close said tip end, and said inturned endmay be turned into the cone tube to any desired extent, so as to providea downwardly extending edge portion. The tip end of the cOne or tube 1is not only inturned, but is preferably smooth, the roughened surface ofthe body of the cone blending into the smooth, in turned surface of thetip.

When the cone tube is in its normal condition,that is, before the tipend thereof has been inturned, such tip end is substantially unyieldingto inward pressure. When, however, the material of the tube has beencircumferentially displaced in the inturning action, then the archeffect existing prior to inturning is materially lost and the twistedportions of the edge, because of their displacement, will more readilyyield inwardly. The inturning action, particularly if effected by a diehaving a movement of relative rotation with respect to the cone tube, asdescribed in the patent above identified, coiir cidently softens thematerial of the tip end portion, thus enabling it to be turned inwardlyand to lay snugly in the die and to receive the smooth, highlydesirable, 001. ished surface. Such softening of the tip end renderssuch tip end less stiff and lacking in rigidity than the body of thetube, it being therefore more pliable and yielding than the bodythereof. This, however, renders the tip end liable to be crushed ordamaged in transportation, inasmuch as such tip end customarilyprotrudes from the yarn mass, as clearly indicated in Figs. 1 and 2. The

object or] my invention is to protect such protruding tip end.Accordingly I provide a protector for such protruding end, saidprotector having a portion adapted to rest upon the adjacent end of theyarn mass and having a portion to receive and thus to protect saidprotruding end. Said protector may be variously constructed toaccomplish my purpose, but preferably it is. formed as a thin sheet ofmetal at or of any other suitable material artificially stifl'ened. Thesaid sheet or disk-like member a has a Hat portion resting upon the endof the yarn mass, and a protruding portion 5 shaped to conformsubstantially to the shape of the protruding tip end. Such protrudingportion 5 may bear lightly upon the protruding end 3 of the conicalsupport when the fiat portion of the protector is in contact with theadjacent end of the yarn mass, but prefer ably I so form the protectorthat the protruding portion 5 thereof is slightly spaced from theinturned tip end 3 of the conical support 2.

It will be evident that in storage and transportation, the pressure towhich the protruding end 5 of the protector is subjected is transmittedalong radiating lines to the flat, disk-like portion of the protector,and thence is conveyed to the yarn mass itself. Thus, the protecting tipend of the support is itself without pressure or without a harmfuldegree of pressure, and therefore all danger of the crushing of such tipend during transportation or in storage is avoided.

The protector a may be made of any suitable thickness and may within thebroad scope and purpose of my invention be formed throughout of athickness equal to the extent to which the tip end 3 protrudes from theyarn mass, said protector having an axial opening or passage to receiveand protect the protruding tip end, but inasmuch as this would add tothe Weight and conse quently to the cost of transportation, I preferablyform said protector as a thin sheet having the protruding, centralportion 5.

Such sheet may be reinforced in any suitable manner, as by ridges orcorrugations, and similarly the protruding portion 5 thereof may beitself reinforced.

forth in the following claims.

Claims:

1. As an article of manufacture, a protector for the protruding end ofthe axial sup port of a Wound yarn mass, having a portion adapted torest upon said yarn mass, and a portion to receive said protruding end.

2. As an article of manufacture, a protector for the protruding end ofthe axial sup port of a Wound yarn mass,having a substantially flatportion adapted to rest upon the end of the yarn mass, and a recessedportion to inclose said protruding end.

3. In combination as an article for trans; portation in commerce, aWound yarn mass, an axial support therefor having a protruding end, anda protector applied to the end of said yarn mass and shaped to receivesaid protruding end.

l. In combination as an article for transportation in commerce, a Woundyarn mass, an axial support therefor having a protruding end, and aprotector applied to the end of said yarn mass and having a central,protruding, recessed portion to inclose the protruding end of saidsupport and adapted loosely to incase the same in spaced relationthereto. i

5. In combination as an article for transportation in commerce, a Woundyarn mass,

a markedly conical, axial support therefor having an inturned tip endprotruding from the yarn mass and a protector applied to the end of saidyarn mass and having a central portion to receive said protruding end.
